This invention relates to heating moves enamelled were in the courses offofdrymg its manu acture, and also other stoves or ovens for variousindustrial purposes,. meluding bread and other baking or cookingoperatlons.

. The invention comprises the provisionwith a chamber or'container forthe articles to be dried, baked, or subjected to heat treatment, simpleand reliablemeans for the efficient transfer to the said chamber of theheat contained in the aseous products of combustion from a urnace(adapted for the burning of gaseous fuel in any e ordinary. manner),whereb the articles placed in such chamber are sub ected to the required"heat treatment with economy, cleanliness and convenience. Referring tothe accompanying sheet of ex lanatory drawings igure 1 is a plan of adrying or like stove constructed in accordance with this invention.

Figure the stove on the line A. A.. (Fi re 1) whilst Figure 3 is asectional end'e evation on the line B. B. in'the direction indicated bythe arrow (F 1);

The same reference letters, inithe difl'er ent views indicate the sameor similar parts.

The chamber a is of. an esuitable construction and providedwi b for theadmission and withdrawal of the articles to be subjected togheattreatment therein. Below the":falee.;jhaae or latform as c'of thechamber, there is p the circuitousl arralzlgld or looped iron or othermetal pi d; e ends e'a'nd-j of such pipe solid, liquid or 2 is asectional side, elevation of :doorssuch as the mixin duct'i associatedin series with thepipe 7 and forming therewith-the conduit or'connectionbetween the delivleg or et f "outlet side/of the blower g and the of thepiped. The communication between the furnace h and the duct 11 iseffected by means ofthe'lateral flue k; the pi "i is in lateralcommunication with the c imney or outlet flue l the said communicationbeing controlled or adjusted by means ere v ve or regulator m. 1 Thejunction of the said lateral the k with the is greferably' formed, asshown at igure' 2 an 3, by a trough or channel a extend' acromtthe saidnot, the sectional area d which is enlarged to receive the trough andprovide the passages 70, adjacent the trough sides," to.; maintain thecommunication belower and upper parts of duct 1'. starting up or puttingthe aforesaidiapparatus into'use, t e valve m is moved into-the positionfor closing or cutting ofl' communication between the blower an the pipe7'; v- By the action of the blower which driven b an electric motor or trough-the belt pu ley p or otherwise) the us products of combustion fromthe n are then drawn through the flue k andduct i to the inlet f of thecircuitous pipe :d,'thence throu h the said pipe (I to the inlet side ofthe b ower.

Having thus describedpur, invention what we claim as new and desire'tosecure by Letters Patent is 1. In stoves I or ovens, the combinationcomprising a chamber, a pipe extending 'circuitously through saidchamber and having its inlet andfoutlet ends'onithe exterior of thechamber wall, a blower with inlet connected to the outlet end of saidcircuitous pipe',.a connection betweenthe outlet of said blower andtheinlet end of 'tlie circuitous v pipe, a chimney, a lateral communicationbetween the said connection and said chimney,

pipe,,a furnace, a ductconnected to the inlet'end of said circuitouspipe, 1: connecting pipe between such duct and the outlet ofsaid blower,a chimney, a lateral communi cation between said connecting pipe andsaid chi1'nney,' a regulator-for said frommunication, and a flue puttingsaid duct in communication with "said furnace, as set forth. 3. Instoves or ovens, the combination comprising a chamber, a pipe extendingcircu'itously through said chamber and having vitsinlet and outlet endson th'e" exterior of the 'chamberwall, a blower with inlet, con

nected to the outlet endof said circuitous pipe, a furnace, aduct-connected to the inlet end of said circuitous ipe, a connectingpipe between saiddufct' and the outlet of said blower, a chimney, alateral-communication betweensaid connecting pipe and said chimi v ney,a regulator for said communication, a flue from said furnace, and atrough extend ing from said flue across said duct and providing thereincentraland side passages, as

set forth. 7 v
